Which process occurs in archaea?
Archaea reproduce asexually through binary fission; the cells split in two like bacteria. In terms of their membrane and chemical structure, the archaea cells share features with eukaryotic cells.
What type of metabolism do thermophiles use?
The maximum growth rate of thermophilic bacteria was found in the exponential growth phase during 2 to 3 hours, and the metabolism was aerobic.
How do archaebacteria grow and develop?
Having no cell nucleus, archaea do not reproduce via mitosis; rather, they procreate using a process called binary fission. In this binary fission process, archaeal DNA replicates, and the two strands are pulled apart as the cell grows. demonstrated that archaea, unlike many bacteria and eukaryotes, produce no spores.
What type of reproduction is archaebacteria?
Archaea reproduce asexually by binary or multiple fission, fragmentation, or budding; meiosis does not occur, so if a species of archaea exists in more than one form, all have the same genetic material.
Do archaea conduct photosynthesis?
Phototrophic archaea use sunlight as a source of energy; however, oxygen–generating photosynthesis does not occur in any archaea.
Is archaea autotrophic or heterotrophic?
Archaea can be both autotrophic and heterotrophic. Archaea are very metabolically diverse. Some species of archaea are autotrophic.
How does a thermophiles make energy?
The thermophiles that thrive in these pools and their runoff channels are heat-loving microorganisms (also called microbes), some of which are descendants of the earliest lifeforms on Earth. Microbes harnessed energy stored in chemicals such as iron and hydrogen sulfide in a process called chemosynthesis.
Is thermophiles autotrophic or heterotrophic?
They are autotrophs, and are the primary carbon fixers in these environments. They are true bacteria (domain bacteria) as opposed to the other inhabitants of extreme environments, the Archaea.
How do archaea process energy?
Some archaea, called lithotrophs, obtain energy from inorganic compounds such as sulfur or ammonia. Other examples include nitrifiers, methanogens, and anaerobic methane oxidizers. In these reactions one compound passes electrons to another in a redox reaction, releasing energy to fuel the cell’s activities.
How do organism of archaebacteria obtain their energy and food?
(1983) have reported that several extremely thermophilic archaebacteria can live with carbon dioxide as their sole carbon source, obtaining energy from the oxidation of hydrogen by sulfur, producing hydrogen sulfide (H2S). They are thus capable of a new type of anaerobic metabolism, a possibly primeval mode of life.
Is archaebacteria autotrophic or heterotrophic?
The six Kingdoms
| A | B |
|---|---|
| Archaebacteria | prokaryote or eukaryote; autotrophic or heterotrophic; unicellular; found in the hot spots of the ocean; some are helpful; ancient |
| Eubacteria | prokaryotes; autotrophic or heterotrophic; unicellular; could be good or bad bacteria |
| Response | the reaction to a stimulus |
Is archaebacteria eukaryotic or prokaryotic?
The archaebacteria are a group of prokaryotes which seem as distinct from the true bacteria (eubacteria) as they are from eukaryotes.
What kind of energy does an archaebacteria produce?
The Archaebacteria are methanogens, i.e., they are capable of producing methane. They act on the organic matter and decompose it to release methane which is then used for cooking and lighting.
What kind of gene flow does an archaebacteria have?
Species are a group with gene flow within its members. The archaebacteria exhibit gene flow across its species. The Archaebacteria are methanogens, i.e., they are capable of producing methane. They act on the organic matter and decompose it to release methane which is then used for cooking and lighting.
How are the cell membranes of Archaebacteria different from bacteria?
Archaebacteria have cell membranes made of ether-linked phospholipids, while bacteria and eukaryotes both make their cell membranes out of ester-linked phospholipids. Archaebacteria use a sugar that is similar to, but not not the same as, the peptidoglycan sugar used in bacteria cell membranes.
